TermDefinition
crest the highest point on a tranverse wave
diffraction the change in direction of a wave when it travels by the edge of an object or through an opening
amplitude the maximum distance a wave varies from its rest position
transverse waves a wave in which the distance is perpendicular to the direction the wave travels
electromagnet wave a transverse wave that can travel through empty space and through matter
mechanical wave a wave that can travel only through matter
compression region of a longitudinal wave where the particles of the medium are closest together
law of reflection law that states that when a wave is reflected from a surface, the angle of reflection is equal to the angle of incidence
longitudinal wave a wave in which the distance is parallel to the direction the wave travels
inference a logical explanation of an observation that is drawn from prior knowledge or experience
trough the lowest point on a transverse wave
waves a disturbance that transfers energy from one place to another without transferring matter
refraction the change in direction of a wave as it changes speed in moving from one medium to another
reflection the bouncing of a wave on a surface
wave length the distance between one point on a wave and the nearest point just like it
rare faction the region of a longitudinal wave where the particles of the medium are farthest apart
transmission the passage of light through an object
frequency the number of wave lengths that pass by a point each second
